Launcher does not launch

Tried launching Minecraft, but it was stuck on "Preparing" for a while now. Unsure if this is an unstable launcher update or something, but I think its somewhat broken. Tried restarting pc but that didn't seem to work so it must be a bug with the launcher itself.

 

EDIT: I am trying to launch Forge 1.8.9 Currently testing other versions and will provide updates.

UPDATES

• launching 1.8.9 was successful
• launching 1.8.9 (OPTIFINE) was successful
• tested many other versions and they were successful. it seems forge may be broken or something
